Problems solved by technology
The disadvantage of the traditional thrust reverser is that, due to the partition between the thrust reverser inner cover and the thrust reverser outer cover, the partition blocks the exhaust of the engine, reducing the thrust and fuel efficiency of the engine

The invention provides a grille reverse-thrust device including a reverse-thrust outer cover, a reverse-thrust inner cover and a plurality of stranglers; the reverse-thrust outer cover is cylindricalin shape, an axial opening extending with the overall length of the reverse-thrust outer cover is arranged on the reverse-thrust outer cover, a grille and a reverse-thrust sliding cover are arranged on the reverse-thrust outer cover, the reverse-thrust sliding cover can move between a retractable state of covering the grille and an opening state of exposing the grille under the action of a reverse-thrust actuating device; the reverse-thrust inner cover is cylindrical in shape and is arranged inside the reverse-thrust outer cover and is radially spaced from the inner surface of the reverse-thrust outer cover, an axial opening extending with the overall length of the reverse-thrust inner cover is arranged on the reverse-thrust inner cover, and the axial opening of the reverse-thrust inner cover is circumferentially aligned with the axial opening of the reverse-thrust outer cover; the stranglers are connected circumferentially with each other and are connected with the inner surface of the reverse-thrust outer cover in a hinged manner; in the retractable state, the plurality of stranglers are attached on the inner surface of the reverse-thrust outer cover; in the opening state, the plurality of stranglers block an annular channel between the reverse-thrust outer cover and the reverse-thrust inner cover. According to the grille reverse-thrust device with the structure, when the stranglers are in the retractable state, gas exhausting of an engine is not blocked, and the thrust and fuel efficiency of the engine are improved.
Description
technical field [0001] The invention relates to an aircraft thrust reverser, in particular to a grid type thrust reverser suitable for a turbojet engine. Background technique [0002] The thrust reverser is an important deceleration device for civil aircraft. It is installed on the nacelle of the turbojet engine. The movement of the thrust reverser drives the relevant components to deflect, thereby turning back the direction of the engine exhaust and decelerating the aircraft. [0003] The thrust reverser generally consists of two parts: the reverse thrust outer cover and the thrust reverse inner cover. The annular passage for engine exhaust is formed between the thrust reverse outer cover and the thrust reverse inner cover. The thrust reverse outer cover and the thrust reverse inner cover are generally designed to be streamlined. To reduce the airflow resistance of the engine exhaust. The reverse thrust cover is generally arranged with a reverse thrust sliding cover, a cho...
